摘要

本文利用二维磁记录（TDMR）技术研究了硬盘驱动器的离轨读取能力（OTRC）。在747测试中测量了偏离轨道的误码率（BER），该测试在一定的线性密度范围内进行。提出了一种高斯模型来拟合由于交叉航迹分离（CTS）而在TDMR头的OTRC浴缸中观测到的双误码率峰。利用高斯模型对双误码率峰的OTRC浴池进行拟合，从而利用TDMR技术增强硬盘驱动器OTRC和挤压致死（S2D）的测量。

Investigation of Offtrack Read Capability in Hard Disk Drive With Two-Dimensional Magnetic Recording (TDMR)

This article investigates the offtrack read capability (OTRC) in hard disk drives utilizing Two-Dimensional magnetic recording (TDMR) technology. The offtrack bit error rate (BER) bathtub was measured in the 747 test, conducted over a range of linear densities. A Gaussian model is proposed to fit the dual BER peaks observed in the OTRC bathtub of the TDMR head due to the cross-track separation (CTS). Using the Gaussian model, we can fit the OTRC bathtub with dual BER peaks, so as to enhance the measurement of OTRC and squeeze-to-death (S2D) in hard disk drives with TDMR technology.
